Karina Smirnoff is set to waltz her way down the aisle!
The Dancing With the Stars pro, 32, is engaged to her baseball player boyfriend Brad Penny, UsMagazine.com has confirmed.
Smirnoff (in a custom-made Marc Bouwer dress) debuted her engagement ring from Penny Saturday at the fifth anniversary party for TAO in Las Vegas. Since Penny couldn't be at the event, he sent another surprise: An EVERLon Diamond Knot necklace Smirnoff discovered after opening a TAO fortune cookie.
The dancer -- who most recently competed on DWTS with Mike "The Situation" Sorrentino -- says Penny asked for her hand in marriage in October after she and Sorrentino performed the foxtrot.
"I was in the middle of the show and had no clue what was cooking behind my back," Smirnoff tells Us, adding that the proposal happened at what she thought was a business meeting. "The dinner meeting was set up at a restaurant in Malibu. When [my manager and I] got there, it was completely empty. She excused herself to take a call and while I was sitting there alone, Brad came in.
"I had crazy hair and black lipstick on and was just concerned about looking like the Bride of Frankenstein," she continues. "Even after Brad got down to one knee and opened the box with the ring, it still didn't register."
The bride-to-be -- who took her romance with Penny public shortly after splitting from DWTS' Maksim Chmerkovskiy in 2009 -- says she's certain her man is The One.
"I'm the happiest I've ever been and Brad is the sole reason for that," Smirnoff tells Us.
